In the embodiment of the invention as illustrated herewith, 1 designates the frame portion of the machine, which may be constructed in any desired manner to properly support the operating mechanism, the frime being preferably formed with a flat-top portion 2 for supporting a part of the mechanism. A main power shaft 3 extends traiiisversely of the frame and is mounted, in suitable bearings carried therebv, the shaft being provided at one end thereof with fixed and loose pulleys 4 and 5, whereby the shaft may be driven from any suitable source of power, the opposite end of said shaft being provided with a hand wheel 6 to permit the mechanism being turned by hand. as may be necessar in adjusting the parts or making repairs. gear 7 is fixed to the shaft 3 and meshes with a gear 8 mounted upon a counter-shaft 9, whereby rotation may be transmitted to the counter-shaft and from the counter-shaft to a longitudinally-extending shaft 10 through suitable intermeshing bevel gears 11 and 12.

Mounted upon an eccentric carried by the shaft 10 is an eccentric strap 14 to which is pivotally connected at 15 a link 17 while an arm 18 formed integral with said strap projects outwardly from said eccentric. The link 17 has its opposite end pivotally connected to one end of a lever 19, as at 20, while the arm 18 is pivotally connected to a lever 22, as at 23. The levers 19 and 22 are pivotally mounted upon a bearing rod 24 supported by the frame and extend upwardly therefrom and operate the feeding mechanism for placing the cartons and the wrappers therefor in proper superposed position preparatory to wra ping the same, as hereinafter described. t will be noted that the levers 19 and 22 are rocked in opposite directions but are both operable directly from a single eccentric 14 thereby effecting a simplification in the operating parts of the machine.

The cartons to be wrapped and the wrappers therefor are fed into the machine transversely thereof and from opposite sides through mechanism actuated by the levers 19 and 22. A supply magazine 25 of the proper size for receiving the cartons, is located adjacent to one side of the machine and may be supported from any suitable portion of the frame. The supply magazine is provided with four side walls 25, 25*, 25, and 25 suitably positioned for the reception of square or rectangular cartons, two of the contiguous walls as 25 and 25 being extended upwardly a considerable distance above the walls 25 and 25 the walls 25 and 25 being preferably each provided with an outturned lip 25 to permit the more ready insertion of the cartons. This construction greatly facilitates the insertion of cartons in the machine since as the cartons are pressed against the upwardly extending sides 25* and 25" they automatically aline themselves and tend to take up such positions as to permit them to readily fall into the supply magazine in proper position to be fed to the wrapping mechanism. The cartons to be wrapped, as indicated at A, are laced in the magazine 25 at a rate substantially equal to the speed of operation of the machine, whereby one, or more, of said cartons is constantly present at the bottom of the magazine. The bottom portion of the magazine 25 is open at the two opposite narrow sides, the wide side portions having inturned flanges 26 'ter of the machine immediatel for supporting the articles and serving as tracks upon which the articles may slide (see Figs. 1 and 3).

A fixed bar 27 provided with oppositelyinclincd beveled faces extends substantially across the machine and serves as a track for a pair of reciprocating carriers 28 and 29, which carriers are connected to the upper ends of the levers 19 and 22. respectively, by means of links 30 and 31. The carrier 29 is mounted to reciprocate beneath the magazine 25 and has pivoted thereto a catch 32 which is normally held in the position shown in Fig. 3 of the drawings by suitable mechanism such as a spring 33 and stop 34. It will be seen upon reference to Fig. 3 of the drawings that when the carrier 29 is moved to the right the catch 32 will engage the lowermost carton A and move the same to the right into position to be wrapped, while upon the return movement of the carrier 29 the catch will be depressed against the tension of the spring 33 by having its inclined upper surface engaged by the lowermost carton but. upon passing the magazine will be released and again assume the position shown in Fig. 3, preparatory to moving the next carton. This construction facilitates the operation of the machine since it permits a carton to drop to the lowermost portion of the magazine immediately after the preceding carton has commenced its movement towards the longitudinal center of the machine, and this insures that a carton be always in position to be moved towards the longitudinal cenupon the return of the carrier to the position shown in Fig. 3 of the drawings thus enabling the carrier to move more rapidly and the speed of the wrapping mechanism to be correspondingly increased. A pair of flanged guides 35 and 36 extend transversely across the machine from the lower flanged sides of the magazine and form a guideway for the package A as it is moved inwardly by the carrier as well as a support for the same after it has been properly positioned relative to the wrapper. (See Fig. 11.) A stop 25 disposed between the flanged guides serves. as an abutment to position the articles accurately with respect to the wrapper when fed forward by the carrier 29.

U-shaped channels 37 and 38 extend transversely of the machine substantially parallel with and above the flanged guides 35 and 36 and at each side thereof, and are adapted to support the wrappers for the cartons in suitable position for applying the same. The wrappers B are fed into the channels 37, 38 by any suitable form of paper-feeding mechanism (not shown) and are deposited therein at a proper point to be engaged by the gripping mechanism supported by the carrier 28 and thereby succes-.

sively brought into position to be applied to the cartons. The carrier 28 supports a gripping head 40, (see Figs. 8. 9 and 10) whlch carries thegripping mechanism and is movable transversely of the machine under the influence of the lever 19. It will be noted that the levers 19 and 22 are soconnected with the eccentric strap that they are moved to draw the carrier for the carton 29 slightly in advance of the inward movement of the wrapper feed carrier 28 so that the succeeding upward movement of the carton toward the wrapper may be started while the wrapper is finishing its inward travel. In this way, the wrapper when it arrives adjacent the center of the machine does not need to wait for the upward movement of the carton which is effected as hereafter described.

Supported by the gripping head 40.is a fixed jaw 41 and a plurality of movable jaws 42 are pivoted to said head, as at 43, and are adapted to move towards and from said fixed jaw. Toggle links 44 and 45 pivoted together at 46 connect the movable aws 42, with the main portion of the gripping head. A shoulder 46' on the head 40 serves as an abutment for the toggle links to prevent swinging of the same beyond the looking position for the jaws 42 as seen in Fig. 8. The pivot pin 46 of these toggle links is extended laterally of the gripping head as shown in Fig. 10 for a purpose which will now be described. A fixed bar 47 extends transversely of the machine adjacent the path of travel of the gripping head and this bar supports stops 48 and 49 properly positioned to engage the pin 46 at points at or near the limits of movement of the gripping head to actuate the toggle links and the movable jaws connected thereto, (see Fig. 2).

As the gripping head moves forwardly to engage the wrapper B (Fig. 8), the edge of the wrapper enters the open space between the jaws 41 and 42 which are presented to the paper in open position and at approximately the same time the pin 46 engages the sto 48 as shown in Fig. 10 of the drawings, t us causing the pin to move rearwardly andthe movable jaws to swing up into position to grip the paper. In this position, the toggle links abutting against the shoulder 46' serve to lock the jaws 42 in their gripping position. As the gripping head is returned to its initial position by the carrier the wrapper is drawn along in the guides 37 and 38, and when the head reaches a point near the limit of the its rearward movement and where it is desired to position the wrapper, the pin 46 strikes .the stop 49, thus moving the links in the opposite direction and causing the movable jaws to drop into the position shown in Fig. 9 and release the wrapper.

Since machines of this character are designed to operate at a high rate of speed, the gripping head must reciprocate rapidly and difliculty might be encountered in having the wrapper jar out of position when released by the jaws. To prevent this movement of the wrapper after it is released and to insure that it be deposited at the same point each time in proper position for engagement by the carton to be wrapped, a dog 50 is provided which is pivotally secured to the gripping head, as at 51, and normally held by ravity in the position shown in Fig. 9. Ilpon reference to that figure. it will be seen that the dog is adapted to grip the edge of the paper slightly after the release of the movable jaws and thus prevent the paper from suddenly jarring out of position in which it is deposited on release of the movable jaws. In order that the dog will not interfere with entry of the edge of the wrapper between the fixed and movable-jaws, a stop 52 is suitably positioned upon the bar 47 to be engaged by the dog as indicated in Fig. 9 of the drawings so that the portion designed to engage the wrapper is depressed to permit the edge of the wrapper to enter the space between the fixed and movable jaws. The jaws are arranged to open while the carrier is still moving and before it has completed its inward stroke whereby the jaws are carried out of engagement with the paper to leave the paper free to be wrapped about the car ton. The paper is placed in proper registering position by striking a stop 50' suitably placed to engage the same while the dog 50 prevents the paper from rebounding after striking the stop and having itself only slight frictional contact with the paper wipes off the same during the completion of the movement of the carrier. The carton A to be wrapped and the wrapper B are thus brought into the machine by suitable mechanism from opposite sides thereof and placed in superposed position adjacent to the longitudinal center of the machine with the wrapper positioned directly above the carton and adapted to be engaged thereby when the article is forced upwardly by the mechanism about to be described.

As previously described, the mechanism for drawing the carton and wrapper towards the longitudinal center of the machine from opposite sides thereof is operated from the single eccentric strap 14 thus simplifying the mechanism and rendering more certain the proper synchronizing of the relative movements of carton and wrapper. The arrangement of the operating mechanism for feeding the cartons and wrappers inwardly towards the center of the machines is preferably such that the wrapper is deposited in s1- tion adjacent the longitudinal center 0 the machine slightly after the carton has been brought into position adjacent the longitudinal center of the machine thus resulting in the carton having started upon its upward movement slightly before or about the time that the wrapper reaches the limit of its inward movement. In this way more rapid operation of the parts can be had since there is no necessity for providing means for permitting lost motion.

Mounted for vertical movement in the machine is an elevator 54 normally positioned below the level of the lowermost carton A in the magazine 25 and which is supported by a vertically-slidable rod 55 mounted for movement in a bearing 56 carried by the frame of the machine. The means for raising and lowering the elevator at proper times comprises a lever 57 pivotally mounted upon the frame, as at 58, and adapted to be oscillated by a can 59 mounted upon the shaft 10 and having a suitable face groove engageable by the roller 60 carried by said lever. The lever has a forked end portion 61 engaging a roller 62 carried by the slidable rod. whereby the rod and the elevator carried thereby are raised and lowered upon oscillation of the lever. The period of movement of the elevator is so timed relative to the feeding mechanism for placing the carton and the wrapper therefor in superposed position in the machine that the elevator starts to rise shortly after the carton has been placed in position and engages the carton to raise the same to the upper position as shown in Fig. l of the drawings. A weighted block 64 carried by a stem 65 slidably mounted in a bearing 66 engages the upper surface of the wrapper above the carton shortly after the carton starts to move upwardly and prevents the wrapper from slipping relative to the carton. This block 64 is capable of free vertical movement for a certain distance where by it occupies a position directly above and spaced slightly from the upper surface of the carton when the carbon has been advanced to a point adjacent to the center of the machine and before it commences its upward movement.

As the carton and wrapper are carried up wardlv by the elevator 54, the wrapper being forced upwardly by the movement of the carton, a curved plate 67 engages one side of the wrapper and smooths the same down over the side of the carton. In a similar manner the opposite side of the wrapper is engaged by a pivoted gate 68 which is springpressed against the carton by a coiled spring 92. The gate 68 engages the carton to be wrapped and thus the sides of the wrapper are folded smoothly against the sides of the carton and drawn closely over the top thereof, the carton and wrapper when in raised position presenting the appearance as shown in Fig. 21 of the drawings wherein the wrap:

' the drawings.

aeoaero per B is drawn over the topof the carton A and the sides a and b of the wrapper extend downwardly therefrom. A line of sets c is ap lied to one edge of the wrapper y any suits 1e means operable as the wrapper is brought into Isosition adjacent the carton and a pivoted ock 69 is located beneath and adjacent to this edge of the wrapper to re vent the posted portion of the wrapper rpm striking against other parts of the machine and depositing aste thereon. Two series of prongs and 1 project upwardly from the lock 69 and as t e wrapper is pulled from the channel 88 it falls upon these prongs and the line of paste is thus prevented from coming in contact with the mechanism. A coiled spring 72 tends to normally hold the block in the position shown in Fig. 1 of the drawings and to return the same to that position if moved therefrom by on agement of the wrapper therewith. A hoo 69 depending from the block 69 is adapted to be engage by the undermost side of the elevator 54 during its downward movement and which engagaement swings the block 69 and prongs 70 an 71 downwardly for the purpose of removing the prongs from. the path of a, 'rapper being fed into the machine. c

When the carton and wrap r are positioned as shown in Fig. 21 of t e drawings, other mechanism is brought into operation for completing the wrapgimg operation. A plate 73 slidab y auppo 3 a standard 74 is actuated at pro or interv by a lever 75 pivotally mounts as at 76, and provided with a roller 77 mounted for actuation by a face cam 78. The plate 73 carries a horizontal folder 80 located adjacent to the edge a of the wrapper when the carton and wrapper have taken the gisition shown in Fi 21 of pen actuation of a plate 73 by the mechanism described, the folder 80, which is provided with a slot 81 formed substantially centrally thereof for the reception of the bracket 82, is slid forwardlv and eng the edge of the wrapper to fold the same eath the carton.

Prior to the forward movement of the folder 80, the elevator 54 is lowered out of the ath of the folder and durin the start of the downward movement of e elevator the carbon is supported above the path of the folder bv the action of the te 68 which presses the carton against the rocket 82.

Immediatel after the forward movement of the folder 0 pushers 83 located above the folder and slidably mounted upon longitudinally-extending rods 84 are forced forwardly to engage the carton and wrapper and force them bodily forwardly in the machine. The Pushers 88 are actuated by an elbow lever 85 pivotally sup orted by t e frame as at 86, and connect to the pusher-s by links 87. A link 88 connects one arm of the elbow lever with a crank 89 carried by the shaft 9, whereby the lever is actuated. The ushers 83 are spaced apart as at QOLFig. 11 to enable the same to pass the bra et 82, and upon forward movement of the anchors they e the article and force t e same forwa y against the ivcted gate 68 which a net the b of the wra per an folds t e same under the article so t at the carton and wraper then assume the form shown in Fig. of the drawin with the ed a and b of the wrapper th folded an or the article and in such a manner that the line of paste 0 carried by the ed 6 lies against the edge a, thus securing a wrapper in tion. The provision of the curved plate 6 makes it unnecessary to ad net the stroke of the sushers 88 so that w on the carton is raise by the elevator 54 the forward edges of the ushers will the flu eamoo yecross wrapper and wipe t the side of the carbon. n other words the distance ushers 83 may be retracted any cm the carton as the latter is raiaedby the elevator and the curved plate 67 will serve to press the flap a closely against the side of the carton as the carton is raised into position to be engaged by the pushers. The pivoted gate 68, being spring pressed into enagement with the o poslte side of the carn, exerts pressure is ereon to hold the carton against the curved glate 67 with Sullicient pressure to insure t at the wrapper be drawn smoothly therearo'und.

The pivoted gate 68 is rotatably mounted on a shaft 91 and is; against the wrapper during forwa. movement of the carton by means of the coiled spring 92 which constantly tends to return the ivoted gate into horizontal position above t e elevator 55, as at 68' (see Fig. 1). As the carton itsegrcssed forwardly by the lungers, the pivo gate is forced mto a d pression 93 whereupon the carton slides over the gate and upon a table 94 extendinaforwardly of the machine. The said table is cut away at the sides on its rear end so that it has a rtion 94' which interfits with plates 152 0 an elevator later to be described and as shown in Fig. 2. As the carton is forced forwardly upon the table, it slides under a pair of pressure bars 95 and 96 arranged longitudinally of the machine.

In order to permit the machine to be used with cartons of diflerent sizes without making it necessary to use a separate machine for each size of carton, the magazine 25 can be readily removed from the machine and a magazine of difl'crent size substituted and at the same time guides 26 for the cartons and guides 37 and 38 for the wra pers may be removed and replaced by gui es of proper size for accommodating the cartons and wrappers with which the machine is to be used. n thus changing the mechanism to permit its use with cartons of difierent size,

llll

of the carton feeding means nor of the rearwardly extending portion of the table 94 which carries the pivoted gate 88 is removed and a similar part also provided with a similar gate 68 substituted therefor in order to space the pivoted to a suitable distance from the curved p to 67 when used with cartons of difl'erent size.

To ad'ust the feed of the carton, the and stop is relocated and the carrier 29 is relaced with a similar carrier having a catch 2 roperly ositioned thereon to efiect the feeding of e carton to the required location with respect to the elevator. To adjust the feed of the wrap er, the stop will be relocated in new nce with variations in the length of the wrapper to be anployed. Obviously, however, if the ch e in size of the carton afiects only its widwhile its length remains the same, it will not be necessary to make any read'ustment e wrapper feeding means.

After the plunger 83 has completed its forward movement, the carton occupies the position indicated by O in Figs. 1 and 2 of the drawings and is then in position for continuing the wrapping o ration by tucking and folding the end portions of the wrapper. Extending transversely of the machine substantially beneath the carton when it assumcs the position as indicated by C- in Fig. 1 after having been forced forwardly by the plunger, is a cross-head 98 having a central depending post 99 slidsbly mounted in ides 100 (see Fig. 4). A roller 101 carried g; the arm 99 is engaged by the forked end 102 of a lever 108 pivotally mounted, as at 104 on the main frame 1 and provided with a roller 105 adapted to engage a cam roove formed in one side of the cam 107, w ch is mounted on the shaft 10 whereby upon rotation of the cam the lover will be oscillated and the cross-head reciprocated in a vertical direction.

The cross-head 98 carries standards 108 and 109 located at o posits ends thereof, and each of these stun ards is provided upon opposite sides with vertical cuttin blades 110 and oflset creasin -blades 11 (See Fig. 15.) The cutting lades 110 have inclined cutting edges 112 located at the u per ends thereof, and the creasing his a 111 are corresponding}; provided with slightly curved upper gas 113. Cooperatin with the creasing blades 111 are crew ing are 112' (Figs. 15 and 16) which are carried by the cutting blades 110 and normal] engage the inner faces of said creasin blades. Each of the standards 108 and 10% is provided with a vertical channel 114 which serves as a guide for a post 115 slidebly mounted therein, each post 115 being provided adjacent its upper end with an end tucker 116 comprising surfaces 116' and 116" at right angles to one another.

(See 18). Each post 115 is located between one air of the oppositelgpositioned sets of his. as previously descri d and the tucker 116 carried by each post is preferably of such size as to near-l fill the space between the opposite sets of b due. A coiled spr' 117 connects each post 115 to its standli i'd 108 which spring yieldingy carries each post with its respective stan ard so that the tucker is elevated slightly above the upper edges of the two sets of blades. The raised position of each post 115 relative to its standfid 108 is limited by a suitable stop piece When the carton has been advanced to a position directly above the standards 108 100 as previously described, the continu movement of the mechanism raises the crowhcad 98 and as the tuckers 116 are normally held in a position above the upper edges of the adjacent blades, the tucker-s first contact with the lower sides of the tubular extended end portions of the wrapper and tuck the some up against the end of the carton in advance of the upper edges of the blades. When the tuckers 116 have moved upwardly to a point substantially on a level with the top surface of the carton, they are stopped by fixed overhanging plates 11B carried by longitudinally-omen ing guide rails 119, whereupon on continued upward movement of the cross-head 98 the blades 110 and 111, advance beyond the tuckers 116, the resiliency of the springs 117 permitting and the parts occupy the position shown in Fig. 16 of the drawings As the blades move upwardly past the tuckers 116, the lower edges of the sides of the wrapper slide between the blades 111 and the creasing bars 112' and a. rease is formed in said wrapper sides as in icated at d in the drawings. The continued upward movement of the blades 110 cause the cutting edges 112 to cut slits a 'thron h the extended portions of the wrapper, t e cutting edges 112 being adapted to wipe past the edges of the plates 118 in order to prevent tear-in of the wrapper and insure a pro r cut in the same.

Immediately ater the u ward movement of the cross-head which rings the arts into the position shown in Fig. 16 o the drawings, the cross-head with the mechanism carried thereby starts downwardly to its lower ition the partially folded wrapper at this stage being shown at Fig. 17 of the drawings wherein the unfolded portion of the wrapper comprises side flaps g and h and a top flap k. During the initial downward movement of the blades 110 and 111, the tuckers 116 remain stationary to hold the tucked end of the wrapper in place and subsequently these tuckcrs 116 are moved away from the tucked end of the wrapper cover while folders carried by the transporter as hereinafter described bend the cover flaps g standards 108 and 109 toga to the position shown in F 18. In this manner the tacked end of wrapper is held in place.

When the machine is used u a other sizes of cartons than that for w ich it is originally constructed the cross-head 98 and (her with the tucker heads 116 and tucking and folding blades associated therewith are removed and a similar structure, the parts of which have the proper proportions, is substituted therefor to insure the proper folding and slitting of the wrappers.

transporter mechanism for carrying the partially wrapped cartons along the table for the further folding o ration will now be described. In fixed posi ion upon opposits sides of the machine are longitudina y-extending supporting frame members 120, each of which is rovided with a longitudinally-extending ct 121 wherein is mounted for reciprocation a trunnion block 122. These members 120 are supported by a transverse bar 180 at their rear ends and are fixed in spaced relation u$lp the tie rod 181 at their forward ends. e tie rod 181 is supported by suitable brackets 183 which are a seed apart and secured to the bed 2 of t e machine. A cross shaft 123 is rotatably mounted in said trunnion blocks and extends transversely of the machine. Adjustably fixed to the shaft 128 are transporter arms 124 each rovided with corner folders 136 see Fi and mounted at such points on t e sha t 123 as to be adapted to properl engage op ite end portions of the partia ly wra pes arton as will be more fully describe The shaft 123 and the trunnion blocks by which it is supported in the slots are reciprocated by means of a link-rod 125 connecting the shaft 123 with the lever in such a manner as to cause forward movement of the shaft to take place at approximately the same time as the advance of the plunger 83.

' The transporter arms 12! serve to transport the cartons from the point where they are deposited by the lungers 83 which point is indicated by C in i 1 of the drawing? to a point adjacent fo ding plates 140. t will be seen upon reference to Fig. 1 of the drawings that the plungers 83 are adapted to move the cartons from their positions upon the elevator to the point indicated by C in Fig. l of the drawings while the transporter arms 124- are given a somewhat shortor range of travel and successively move the carton from a point where they are deposited b the plungers 83 forwardl into sition or thepaste to be applied ereto. us, the transporter arms 12tmust ad- Vance with each forward movement of the plungers 83 but are not required to move as great a distance. transporter arms 124 to be operated by the is relation permits the lever 85 which operates the plungers 83, the rod 125 for operating the transporter arms being connected to the lever 85 nearer to its pivot point than are the plungars 88 since the transporter arms areto travel a shorter distance than the plungers.

The transporter arms 124 are double ended as shown and each end of each arm 12ft is provided with corner folders 136 com prising anfile plates with a portion 187 for engaging t e end of the carton and portion 138 for foldi the. corner flap g of the wrapper (see 1g. 7).

order to secure groper operation of the transporter arms an to suitably time the movement of the same, relative to the other parts of the mechanism, a pair of double ended cranks 121} and 127 are fixed to the shaft 128 one ad acent each end thereof for controlling the rotation of the shaft and the rotatlve movement of the transporter arms. (See Fig. 6.) The double crank 126 is located at the right end of shaft 123 looki forwardly of the machine and is provi ed with rolls 128 located at opposite ends thereof, and the double crank 127 is located at the left end of said shaft 123 and is rovided with similar rolls 129. The dou le crank 126 is so positioned u on the shaft 128 that one of the roll carrie thereby will be in ition to engage a slot 130 formed in a xed boss 181 carried by the bar 120 which is at the right of the machine while the double crank 1 is located at such a point that the rolls 129 carried thereby are adapted to run in and out of a moove 132 formed in a lever arm 133 pivotally supg lilrted as at 184 lag one of the brackets 183.

e travel of don le crank 127 is such that one or the other of its rolls 129 is constantly within said slot 132.

The lever 188 is pivoted to a fixed support as at 134 and has pivotally attached thereto as at 184' a two-part link 156 the arts of which are capable of slight lonmtu-linal movement relative to each other. The link 156 is actuated by the earn 107 to reciprocate the same a suflicient degree to insure pro r actuation of the lever 183.

on the lever 85 draws the link I25 and the shaft 123 rearwardly, the transporter starts to move rearwardly of the machine and the link 156 is drawn slowly downwardly thus drawing the lever 133 into its downwardly inclined osition as, indicated by the inclined dotte line in Fig. 25 of the drawings. The rearward roll 129 being in the slot 132 is drawn downwardly with the lever and thus rotating the shaft- 123 in a counter-clockwise direction as seen in Fig. 6. As the shaft 123 is rotated. the forward roll 129 which is outside the slot, as shown in Fig. 26 of the drawin swings npwardl through an arc-she e path as indicate by the arrows in lg. 25. The

forward roll 128 is also swung upward] through an arc-shaped path nearly para leling the curved path traversed by the roll 129. As the shaft 123 is thus rotated, the rearward roll 128 is drawn downwardly into the intermediate )OSltlOn indicated in Fig. 25 of the drawings and wherein the cross-heads are shown as being substantially vertical. The slot 130 serves as a stop to hold the rearward roll 128 against further rearward movement and thus com el continued anti-clockwise rotation of t e shaft 123 as it moves rearwardly.

As the shaft 123 continues its rearward movement the lever 133 is movedupwnrdly by the link 156 until itrcaches its normal horizontal sition when an adjustable sto 133' carried liy the lever 133 abuts a shou der 183' to prevent further upward movement of the lever 133, and insuring that the slot 132 will occu y a horizontal position as the shaft 123 is su sequently moved forwardly. The two-part link 156 is provided with a coiled compression spring 156 as shown in Fig. 6 which permits a slight overthrow of the cam 10? to hold the lever 133 in horizontal position for a suitable periodi thus making it unnecessary to require such socurate machining of the cam as would otterwise be necessary and also permitting proper adjustment in the position of the lever 133 through the adjustable stop 133. The lower portion of the link 156 may slide upwardly in the sleeve carried by the upper portion against the force exerted hv the compression spring 156' during the overthrow of the cam 10?, as will be seen upon ins tion of Fig. 6 of the drawings.

us, when the transporter commences its forward movement the lever 133 is in horizontal position and remains in that position to serve as a guiding and controllm means for the trans rter until the trans porter has reached t e limit of its forward movement.

When the shaft 123 is located at the limit of its rearward movement, as when the plunger S3 begins its forward movement the transporter arms 124 are substantially vertical and the forward roll 129 is positioned within the slot 13:2 formed in the lever arm 133 which arm is at that time in such osition that the slot 182 is substantially ori' zontal and rallel with the slot 121, wherelizg upon lght forward movement of the aft 128 the rearmost roll 129 also enters the slot 182 and any tendency of the shaft 128 to rotate is resisted by the double crank 127 and the lever arm 133.

As the shaft 123 moves rearwardl from its intermediate position as shown in Fig. 25 of the drawings, it will be rotated approximatel d ees in a counter-clockwise direction to bring the cross-heads into substantially horizontal pomtion. As the shaft is thus rotated the transporter arms 124 are rotated substantially 90 degrees and these arms thus assume a substantially vertical position as shown in Fig. 1 of the drawings. As the transporter arms are thus rotated the angular wrapper folding portion 138 of the plate 131 carried by each arm rotates into engagement with the flap g of each end of the wrapper closely adjacent to the end of the carton and folds the same closely against the end of the carton and into the position illustrated in Fig. 18 of the drawing. When the flap has thus been folded into place. the portion 137 of the plate 136 en gas the carton and forces the same forwu ly with the continued forward travel of the transporter arms. It is to be understood that one of these transporter arms is located at each end of the carton, whereby both ends of the wrapper are simultaneously folded and the carton moved forwardly uniformly at both ends. As the carton is thus moved forwardly, the flu s h are engaged by rearwardly project lding plates 140 (see Fig. 2) and fc ffiled in against the flaps g previously folded by the transporter arms.

The package then assumes the form shown in Fig. 19 of the drawings, wherein the flaps g and I: have been folded in sition and the dportion k extends outward y from each en of the package. As the transporter arms continue to advance the pack age alon%) the table 94, it is brought into position adjacent the foldin plates 140 and the oppositely extending ps I: rest upon the uppermost edges 140 of the foldlug plates 140 while the package is held in osition upon the table 94 by the pressure are and 96. The packs e remains in this D position until advance to position E g and is advanced to E position by the advance of a package being ushed along the bed by the transporter. en advancing from its D to E position the flaps k are drawn under corrugated plates 144 positioned above the paste receptacle while the aclrage is held in position upon the table Ty the pressure of bars 95 and 96. (See figs. 2, 6, 18.)

hafte 145 and 146 are located upon opsito sides of the machine and mounted or oscillation in suitable bearings 147 and 148, respectively. Fixedly secured to one end of each shaft 145 and 146 are crank arms 149 and 150 positioned above the paste receptacles 142 and 143, respectively, and capable of being partially immersed in the mate contained therein u on suitable oscilation of said shafts. n the package is positioned at E and opposite'the paste receptacles and at which time the flaps kpro'oct under the plates 144. the shafts are osci lated by means which will be more fully described hereinafter to raise the crank arms corrugations in its travel an actuated from the shaft 10 149 and 150 and the bars 151 carried thereby to ress the barsagainst the under surface 0 thereto. It wi be understood that the bars 151 are so located as to re ister with the formed in t e corrugated plate 144 when they are raised and thus prevent paste coming into contact with any part of the machine, or being deposited where it can come into contact with the outer surface of the package. The pasteapplying mechanism is timed to operate w en the packa e, reaches the proper oint the package is force forwardly from this point by the pressure imarted to successive packages as they are rought forwardly by the transporter arms. From this point the package is advanced as succeeding packages are brought into paste appl ing position until it is deposited upon an e evator 152 for completion of the folding operation.

Immediately after delivering the package to the position D, the transporting mechanism, which has reached the limit of its forward movement, starts to return to its initial position in the manner previously described. When the package is being forced forwardly by succeeding packages, as previously described, the flaps k, to which paste has been applied, extend outwardly from opposite .ends of the package beneath oppositely positioned ro lers 160 located at opposite ends of the elevator. (See Fig. 5.) The elevator 152 is supported by a post 161 slidably mounted for vertical movement in a guide 163 carried by the frame and is by mechanism which will now. be described. A crank 164 carried bythe shaft 10 has a, crank-pin 165 movable m a slot 166 formed in one arm of an elbow-lever 185 which is pivotally mounted upon the frame, .as at 167. The

other arm of the elbow-leverhas a forked end 168 engaging a roller 170 carried by the post 161, whereby upon rotation of the shaft Y10 and post 161' and the elevator carried thereby are raised and lowered a distance equal to or somewhat greater than the thickness of the package. As the package is raised by the elevator, the rollers 160 press against the flaps k and force them closely V against the ends of the package, thus bin ing all parts of the wrapper around the article and com letely closing the package. As each succeeding package is raised )y the elevator, the preceding packages are forced upwardly through a discharge chute 17-1 provided on o posite sides with a pluralitv of brushes 1 2 for engaging the ends of the packages and preming the pasted flaps closely against the .ends. As Wlll be noted upon reference to Fig. 5 of the drawings, the brushes 172 are upwardly inclined the flalps and apply lines ofwpastefiwhich and are sufiiciently still to hold the packainst falhng during the time in i the, elevator is returning to its lowered position t'oh'eceive another package.

The mechanism for oscillating the shafts 145 and 146 com rises cranks 145 and 146' journaled upon t e ends of these shafts o posite the cranks 149 and 150. The cranks 145 and 146' are provided with rolls 174 and 175, respectively, which are positioned in a horizontal slot 176 provided m a plate 177 secured to the post 161 adjacent to the elevator 152 and movable vertically herewith under the influence of the elbow-lever 185. Cranks 145" and 146" arekeyedor otherwise secured to the shafts 145 and 146 respectively and. located hdjacent to the cranks 145' and 146, 'to which they are respectively secured to pr vide means for oscillating the shafts 145 and 146 in a manner which will permit'an adjustment of the degree of oscillation to; be imparted to the shafts 145 and 146 and consequentl an adjustment of the amount of throw be imparted to the cranks 149 and 150. The means for adjustably securing the cranks 145" and 146" to the cranks 145 and 146 respectively is best illustrated in connection with the cranks 145' and 145' in Fig. 5 of the drawings and as the means for connectin the cranks 146 and 146" is the same in :11? respects only one of these connecting mechanisms will be described in detail. The crank 145 as previously stated is ke ed or otherwise secured to the shaft 145 an is provided adjacent. its end with a in 188 which is adapted to project throng a slot 187 formed in the crank 145. and a nut 189 is adapted to be threaded upon the pm 188 to firml clamp the crank 145 to the crank 145'. e

The pressure bars 95 and 96, asteroce tacles 142 and 143, rolls 160 an separate sidhs of the discharge chute 171, are mounted upon two castings 190 and 191 res 1 located upon 0 'posite sides of t e machine. and ad ustab y mounted upon a transverse bar 193. By means of'this arrangementof the parts, the opposite pressure bars, paste receptacles, wipin rollers and sides of the delivery chute, may adjusted towards or from the longitudinal center of the machine by adjusting the castings. to different sitions u n the bar 193. The slot 176 tiveormed in t 0 plate 177 permitsthe 'wctuaand from each other this part of the wrapping mechanism can be readily adjusted to accommodate packages of different lengths and thus enable the machine be eas lfy and quickly changed to wrap articles of di ferent sizes.

After the machine is once placed in operation, a succession of articles continue to travel therethrough, and when one package has been forced into position opposite the folding plates by the transporter arms, a previously folded carton is forcedby it to a position op osite the paste applylng receptacles and ally on to the elevator 152 and against the stop 181 carried thereby 1n p081 tion to be raised by the next upward movement of the elevator. After the elevator has raised the article a sufficient distance and consequently forced a plurality of preceding articles upwardly, the elevator returns to its initial position to receive the next article as forced from the table 94. The table 94 is provided with a portion 94' of reduced width which projects within a slot 152' formed in the elevator 152 whereby when the elevator' is drawn downwardly below the level of the table 94 the acka 'e supported by the extreme end of t e tabe is prevented from following the elevator 1n its movement below the table but is suported by the table in position to be engaged by the elevator in its upward travel and raised into enga ement with the brushes carried by the discharge s out 171. This construction also permits the operation of the elevator by a simple crank mechanism thus rendering unnecessary the use of complicated cams for retaining the elevator at the level of the table for a suflicient period of time to ermit the package to be de osited thereon. uring the time when the e evator is moving u wardly the cranks 149 and 150 are actuate to apply paste to the flaps 7c of a succeeding ackage since at this time the cartons are not ing advanced by the transporters. The paste receptacles 142 and 143 are provided res ectively with drain spouts 142' and 143 eac of which is pivotally carried by its paste receptacle whereb the drain spouts may each be rotated to a ownwardly extending position as shown in dotted lines in Fig. 5 of the drawings whereby the paste may be entirely removed from each receptacle when the machine is not in use. i

The various mechanisms engaging the carton and the wrapper therefor, are all capable of adjustment to permit the machine to operate upon articles of different size. The

pressure bars and 96 are adjustable to accommodate articles of different thickness, while the transporter arms are adjustably mounted on the shaft 123 to properly operate upon articles of different length. The necessary adjustments for adapting the machine for use with articles of difierent size may be readily efl'ected b manually shifting the adjustable parts, t us makin it unnecessary to construct separate machines for use with articles of different size.

In the operation of the above-described mechanism the articles to be wrapped are constantly fed into the magazine 25 by any suitable means, whereby a constant supply of articles is maintained and rendered acces'sible to the carrier 29 for feeding to the wrapping mechanism. In a similar manner, any suitable form of sheet-feeding mechanism may be used for feeding wrappers into the guide channels 37 and 38 in position so that each succeeding wrapper may be engaged by the gripping head on each outward movement. thereof. As the article to be wrapped and the wrapper therefor are placed in superposed position in the machine, 'the elevator 54 is actuated to force the article and wrapper upwardly to the level of the table 94 along which they are advanced and the wrapper folded around the article in the manner set forth. The transporter mechanism leaves each package at a point opposite the folding plates 140 and then begins its return movement during which the transporter arms are rotated at 180 degrees in order to bring the transporter arms behind the next package and force it forward in the same manner as in the previous operation, While the transporter arms are returning to engage the next succeeding package. the elevator 152 is actuated to raise the package placed thereon and returns to lowered position in time to receive another package as a package is again brought forward by the transporter arms.
